[0002] The present disclosure generally relates to systems and methods for processing data records in a wireless telecommunications network. The present disclosure relates to a system and a method for network function integration with geographical (GEO) file transfer protocol (FTP) servers. More particularly, the present disclosure relates to a system and a method for transferring a plurality of files to FTP servers.DEFINITION

[0003] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used to indicate otherwise.

[0004] The expression ‘File Transfer Protocol (FTP) servers’ used hereinafter in the specification refers to specially designed systems to facilitate the transfer of files between computers over a network, typically the Internet. FTP servers provide a standardized way for users to upload, download, and manage filesstored on a remote server. FTP servers use the FTP protocol to establish connections and transfer data securely (in some cases, encryption may be employed).

[0005] The expression ‘Geographical (GEO) server’ used hereinafter in the specification refers to a server that is organized or categorized based on geographic regions or locations. GEO server is often used in scenarios where users need access to location-specific data or resources, such as geographic information systems (GIS), weather data, maps, or regional software updates. It can also be used by organizations with distributed operations or customers around the world to provide localized content or services efficiently.

[0006] The expression ‘packet data network gateway (P-gateway)’ used hereinafter in the specification refers to a key element in the Long-Term Evolution (LTE) or Evolved Packet Core (EPC) network architecture. P-gateway serves as the point of interconnection between the LTE radio access network (RAN) and the external packet data networks, such as the Internet or private corporate networks.

[0007] The expression ‘policy control function (PCF)’ used hereinafter in the specification refers to a key component within the 5G Core (5GC) network architecture. The PCF is responsible for controlling and enforcing policies related to Quality of Service (QoS), network resource allocation, and user access control. The PCF interacts with other network functions to ensure that the network resources are utilized efficiently and that subscribers receive the appropriate level of service based on their subscription, application requirements, and network conditions.

[0008] The expression ‘policy and charging rules function (PCRF)’ used hereinafter in the specification refers to a component of the 3rd Generation Partnership Project (3GPP) architecture used in 4G LTE and 5G networks. The PCRF is responsible for controlling and managing policies related to both the quality of service (QoS) and charging aspects of the network.

[0009] The expression ‘XDR (any(X) Detail record)’ used hereinafter in the specification refers to a type of data file commonly used for storing structured data. In a specific implementation, XDR can be used to express any of CDR (Call data record), MDR (message data record), UDR (user data record), and SDR (session data record).

[0010] The active state refers to a condition where a component, feature, process, or system is currently operational, functioning, or ready to perform its intended tasks.

[0011] These definitions are in addition to those expressed in the art.BACKGROUND OF THE INVENTION

[0012] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admission of the prior art.

[0013] In telecommunication networks, error logs and counters are not sufficient to identify the issue. Therefore, extended detection and response records are used to record different sets of information required for end-to-end debugging. If time-sensitive packet switch (TPS) is high, then a network function (NF) may not be able to provide the required output, and moreover, the NF may not be able to save extended detection and response records for a longer period due to hard disk space limitations. Conventional systems have a slower debugging process that is inefficient.

[0014] There is, therefore, a need in the art to provide a system and a method that can mitigate the problems associated with the prior arts.OBJECTS OF THE INVENTION

[0060] As portable electronic devices and wireless technologies continue to improve and grow in popularity, the advancing wireless technologies for data transfer are also expected to evolve and replace the older generations of technologies. In the field of wireless data communications, the dynamic advancement of various generations of cellular technology are also seen. The development, in this respect, has been incremental in the order of second generation (2G), third generation (3G), fourth generation (4G), and now fifth generation (5G), and more such generations are expected to continue in the forthcoming time.

[0061] While considerable emphasis has been placed herein on the components and component parts of the preferred embodiments, it will be appreciated that many embodiments can be made and that many changes can be made in the preferred embodiments without departing from the principles of the disclosure. These and other changes in the preferred embodiment as well as other embodiments of the disclosure will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the disclosure and not as a limitation.

[0062] At present, in a network, files are stored locally, i.e., in a local server. For example, the price of postpaid service is calculated by using a call detail record, which is sent to the billing system after the call is made. These records (also known as charging detail records or event detail records and often abbreviated as CDRs, EDRs, or, more generally, XDRs) are grouped together by Mobile Switching Centers (MSCs) or other service enabler modules of the network and sent as XDRs file to a billing system. This XDRs file remains stored in the billing system.However, there are several challenges with the local server, which are primarily related to limited storage capacity, inefficient file organization, and potential security vulnerabilities. These issues are significantly hindering workflow, collaboration, and productivity among employees. Inadequate file management has resulted in confusion and redundancy, and the lack of robust backup procedures and security measures poses imminent risks of data breaches and loss.

[0063] To address these issues, it is required that a network operator take immediate action by integrating cloud storage solutions for scalability, implementing a comprehensive file management system for better organization, establishing regular backup protocols, and employing a scalable server infrastructure to ensure efficient file storage and management. Hence, a system and a method are required to address the aforementioned issue.

[0064] The present disclosure discloses a system and a method to efficiently manage and store records of longer periods, facilitating future troubleshooting. The present disclosure uses at least one File Transfer Protocol (FTP) server, where either a Policy Control Function (5G PCF) or a Policy and Charging Rules Function (PCRF) transfers the files to a primary FTP server while continuously monitoring the connection. In case of any issues with the connection, the PCRF or the PCF promptly switches to a secondary FTP server and completes the file transfer. Furthermore, as a default, the primary server is prioritized over the secondary server, ensuring a streamlined and effective process.

[0065] The data records, such as files, are stored at a remote address (remotely placed servers) using a configurable parameter. The configuration parameter may be configured while configuring the application (system). The configuration parameter contains the details (Hostname / IpAddress) of the server where the files need to be stored.

[0066] In an embodiment, several FTP managers are used to handle connectivity issues. A secondary manager can be used if the primary manager hasconnection problems. If a network function (NF) cannot log in to the FTP server, the system is configured to automatically turn off sending of files and send a notification. The network function (for example PCRF or PCF) regularly transfers the files from a local server, which helps to speed up debugging and reduce the turnaround time.

[0067] The various embodiments throughout the disclosure will be explained in more detail with reference to FIG. 1- FIG. 6.

[0068] FIG. 1 illustrates an example network architecture (100) for implementing a system (200) for transferring a plurality of files to one or more remotely placed servers, in accordance with an embodiment of the present disclosure. In an aspect, the one or more remotely placed servers include a local server, a primary server, and a secondary server. In an aspect, the number of servers may be varied according to the requirements of a network operator.

[0069] As illustrated in FIG. 1, one or more user devices (104-1, 104- 2...104-N) may be connected to the system (108) through a network (106). A person of ordinary skill in the art will understand that one or more user devices (computing devices) (104-1, 104-2...104-N) may be collectively referred to as computing devices (104) and individually referred to as computing devices (104). One or more users (102-1 , 102-2. . .102-N) may provide one or more requests to the system (108). A person of ordinary skill in the art will understand that one or more users (102-1, 102-2...102-N) may be collectively referred to as users (102) and individually referred to as users (102). Further, the computing devices (104) may also be referred to as user equipment (UE) (104) or as UEs (104) throughout the disclosure.

[0070] In an embodiment, the user equipment (UE) (104) includes, but not be limited to, a mobile, a laptop, etc. Further, the computing device (104) may include one or more in-built or externally coupled accessories including, but not limited to, a visual aid device such as a camera, audio aid, microphone, or keyboard.Furthermore, the user equipment (UE) (104) may include a mobile phone, smartphone, virtual reality (VR) devices, augmented reality (AR) devices, a laptop, a general-purpose computer, a desktop, a personal digital assistant, a tablet computer, and a mainframe computer. Additionally, input devices for receiving input from the user (102), such as a touchpad, touch-enabled screen, electronic pen, and the like, may be used.

[0071] In an embodiment, the network (106) includes, by way of example but not limitation, at least a portion of one or more networks having one or more nodes that transmit, receive, forward, generate, buffer, store, route, switch, process, or a combination thereof, etc. one or more messages, packets, signals, waves, voltage or current levels, some combination thereof, or so forth. The network (106) also includes, by way of example but not limitation, one or more of a wireless network, a wired network, an internet, an intranet, a public network, a private network, a packet- switched network, a circuit- switched network, an ad hoc network, an infrastructure network, a Public-Switched Telephone Network (PSTN), a cable network, a cellular network, a satellite network, a fiber optic network, or some combination thereof.

[0072] Although FIG. 1 shows exemplary components of the network architecture (100), in other embodiments, the network architecture (100) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 1. Additionally, or alternatively, one or more components of the network architecture (100) may perform functions described as being performed by one or more other components of the network architecture (100).

[0073] FIG. 2 illustrates a block diagram of the system (200) for storing the plurality of files into one or more servers. The system (200) is configured to transfer files via a network function (204) to an FTP server in accordance with anembodiment of the present disclosure. In an example, the FTP server may include a primary server (212), and a secondary server (214).

[0074] As illustrated in FIG. 2, in an embodiment, the system (200) includes at least one packet data network gateway (P-gateway) (202), the network function (204), the primary server (212), and the secondary server (214). The network function (204) includes a file manager (206), a local server (208), and a schedular (210). In an example, the network function (204) is a policy control function (PCF), a policy and charging rules function (PCRF), or a converged PCF having functionalities of PCF and PCRF. The PCF is responsible for controlling and enforcing network policies related to Quality of Service (QoS), traffic management, and network resource allocation. The PCF interacts with other network elements such as the Access and Mobility Management Function (AMF) and the User Plane Function (UPF) to ensure that the policies defined for each subscriber are applied correctly. The PCRF defines and enforces policies related to QoS, network resource allocation, and traffic management. These policies ensure that different classes of services (like voice, video, data) receive appropriate priority and resources within the network. In an operative aspect, before initiating the process of transferring the files to the FTP server, the system (200) may be configured to determine whether a flag is enabled or not. The flag refers to a variable or a value that serves as a signal or indicator of a certain condition or state within the system. For example, if the flag is enabled, then a connection may be established between the network function (204) and the FTP server (including the primary server and the secondary server) for exchanging the files. If the flag is disabled, then no connection can be established.

[0075] The network function (204) is configured to receive the plurality of files from a plurality of user equipments via at least one P-gateway (202). In an aspect, the plurality of files includes a data file, a video file, and an audio file. The P-gateway (P-GW) (202) serves as an ingress and egress point to a 5G Core (5GC) network from a PDN (Packet Data Network) such as the Internet. When a subscriber(user) establishes a connection to a given PDN, the P-GW serves as a point of attachment to that PDN. Packet filtering is a key role of the P-GW in order to ensure that downlink data has the appropriate QoS applied. The P-GW (202) manages the mobility of devices within the network, including tasks such as assigning IP addresses to devices, tracking their location, and managing handovers between different base stations.

[0076] The local server (208) is configured to store the received plurality of files. The local server (208) refers to a server that is located within a local network, typically within an organization or a specific physical location.

[0077] The file manager (206) is configured to format each of the received plurality of files and generate a plurality of formatted files. In an aspect, to format each of the received files, the file manager (206) may be configured to employ a set of formatting steps on each received file according to a specified format or structure to produce the formatted steps. In an aspect, the set of formatting steps may include converting the received files from one file format to another format, extracting specific data fields from the received files by employing parsing, and employing normalization of data within the formatted files to generate a consistent format. To begin the conversion of the received files from one file format to another format, the file manager (206) ascertains a specific file format for each file (For example, PDF, DOCX, JPG, MP4, etc.). Then, the file manager (206) considers and selects a desired format to which conversion of these files is required. This chosen format could be a widely used standard or one that is tailored to meet the unique and specific needs of a network operator. Further, the file manager (206) may be configured to validate the content and structure of the formatted files to ensure they meet a predefined criterion. The predefined criterion may include a size of the file, a compression ratio, and a type of the formatted file (editable or non-editable). In an embodiment, the plurality of formatted files is an XDR file or an abstract syntax notation (ASN) file. The local server is configured to store the plurality of formatted files. In an aspect, the file manager (206) serves as a central hub for navigating,organizing, and manipulating files and directories on the local server. The file manager (206) facilitates tasks such as copying, moving, renaming, and deleting files and directories, while also providing features like file preview, search, sorting, and filtering to enhance efficiency in file management. Additionally, the file managers often offer capabilities for viewing detailed file properties, compressing, and extracting files, sharing files with others, and performing batch operations, collectively empowering users to manage their digital content and streamline their workflow efficiently.

[0078] In an aspect, the scheduler (210) is configured to determine a number of parameters associated with the local server. In an aspect, the scheduler (210) may be configured to send a query to the local server. For example, the query may include a number of details to be asked the local server. In an example, the query may be an update signal regarding “a current storage of the local server”. Upon receiving the query, the local server processes it and prepares a response. Based on the received query, the local server may be able to provide the response having the current storage of the local server. Further, based on the response received from the local server, the schedular determines the number of parameters. In another example, by sending the query to the local server, the schedular is configured to determine the number of parameters. In another example, the schedular may include a range of values corresponding to each parameter such that the scheduler (210) either chooses one of the primary server (212) or the secondary server (214). In an example, the number of parameters includes a current storage of the local server, a maximum storage of the local server, and a time period up to which the plurality of files needs to be stored. For example, if the schedular (210) determines that the local server is about to reach its maximum capacity of storage, then the scheduler (210) is configured to establish a connection with the primary server (212) and the secondary server (214) based on the determined parameters. In an aspect, each of the primary server and the secondary server is a file transfer protocol (FTP) server or a geo-server. The scheduler is configured to establish a first connection with the primary server based on the determined parameters. To establish the firstconnection with the primary server, the scheduler (210) may be configured to send a request to connect to the primary server. If authentication credentials are required, the scheduler (210) may include them in the connection request. The primary server may acknowledge the first connection or provide an error if the first connection cannot be established.

[0079] The scheduler (210) is configured to monitor a state of the first established connection. To monitor the state of the first established connection, the scheduler (210) may be configured to opt for the heartbeat mechanism, in which the scheduler (210) periodically sends heartbeat signals or ping requests to the primary server to verify that the connection is still active. In another example, the scheduler (210) may listen for updates or notifications from the primary server to maintain the relevance of the connection. The scheduler (210) is configured to transfer the formatted files to the primary server if the monitored state of the first established connection is an active state. The active state represents an operational status of the first established connection between the scheduler (210) and the primary server. It signifies that the connection is currently established and functioning properly, allowing for the exchange of files or signals between the scheduler (210) and the primary server.

[0080] If the monitored state of the first established connection is a down state, the scheduler (210) is configured to establish a second connection with a secondary server. The down state indicates that the connection is not operational or unavailable. The down state signifies that communication between the scheduler (210) and the primary server cannot occur, preventing the exchange of files or signals as intended. To establish the second connection with the secondary server, the scheduler (210) may be configured to send a request to connect to the secondary server. If authentication credentials are required, the scheduler (210) may include them in the connection request. The secondary server may acknowledge the second connection or provide an error if the second connection cannot be established. Afterestablishing the second established connection, the scheduler (210) is configured to transfer the formatted files to the secondary server.

[0081] In an embodiment, the system (200) is configured to maintain a list pertaining to the first established connection, including a number of files successfully transferred and a number of files waiting to be transferred. This functionality allows the system to provide real-time updates on the status of each file transfer operation, ensuring transparency and efficiency in data exchange processes. By continuously updating the list throughout the connection establishment phase, the system enables administrators and users to monitor the flow of data, promptly address any transfer delays or interruptions, and maintain optimal performance of network resources.

[0082] In an embodiment, the network function (NF) (204) is configured to transfer the formatted files along with a configurable parameter having at least one detail of the primary server (212) and the secondary server (214). In an example, the at least one detail includes an Internet protocol (IP) address, a domain name, a host name, and a universal resource locator (URL) address.

[0083] In an embodiment, the system (200) is configured to transfer the stored file from the local server to at least one of the primary server and the secondary server after a predefined time. In an example, the predefined time refers to a specific time that is established or set in advance based on predefined criteria or requirements. For example, the predefined time lies between 15 minutes and 15 days. For example, the system (200) is configured to transfer the stored file from the local server to at least one of the primary server and the secondary server after 1 hour.

[0084] FIG. 3 illustrates an exemplary block diagram (300) of the network function (NF) (204), in accordance with an embodiment of the present disclosure.

[0085] Referring to FIG. 3, in an embodiment, the network function includes a receiving unit (302) and a processing unit (308). In an aspect, thereceiving unit (302) is configured to receive the files directly from the user equipment, a plurality of network modules or any other sources (third party source). In an example, the files may also be stored in cloud-based services, either provided by the network operator or third-party service providers. These could include storage services, databases, and content delivery networks. In another example, the user records may be received from subscriber data management (SDM) systems. The SDM systems manage subscriber data across different generations of networks and may integrate with 5G core network functions to ensure seamless service continuity. In an example, the file is the XDR file referring to any of CDR (Call data record), MDR (message data record), UDR (user data record, and SDR (session data record).

[0086] The processing unit (308) may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and / or any devices that process data based on operational instructions. Among other capabilities, the processing engine may be configured to fetch and execute computer-readable instructions stored in a memory (304) of the network function. The memory (304) may be configured to store one or more computer-readable instructions or routines in a non-transitory computer readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory (304) may comprise any non-transitory storage device including, for example, volatile memory such as random-access memory (RAM), or non-volatile memory such as erasable programmable read only memory (EPROM), flash memory, and the like.

[0087] In an embodiment, the network function may include an interface(s) (306). The interface(s) (306) may comprise a variety of interfaces, for example, interfaces for data input and output devices (I / O), storage devices, and the like. The interface(s) (306) may facilitate communication through the network function. The interface(s) (306) may also provide a communication pathway for one or more components of the network function. Examples of such components include, butare not limited to, processing unit(s) (308) and a database (310). Further, the processing unit(s) (308) may include a data parameter engine (312) and other engine(s) (314). In an embodiment, the other engine(s) (314) may include, but not limited to, a data ingestion engine, an input / output engine, and a notification engine.

[0088] In an embodiment, the processing unit (308) may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing unit (308). In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing unit (308) may be processor-executable instructions stored on a non- transitory machine -readable storage medium and the hardware for the processing unit (308) may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine- readable storage medium may store instructions that, when executed by the processing resource, implement the processing unit(s) (308). In such examples, the system may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the system and the processing resource. In other examples, the processing unit (308) may be implemented by electronic circuitry.

[0089] Although FIG. 3 shows exemplary components of the network function, in other embodiments, the network function may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 3. Additionally, or alternatively, one or more components of the network function may perform functions described as being performed by one or more other components of the network function.

[0090] FIG. 4 illustrates an example flow diagram (400) of file transfer between the NF (204) and the FTP server, in accordance with an embodiment ofthe present disclosure. As illustrated in FIG. 4, in an embodiment, the flow diagram (400) may include the following steps.

[0091] At step 402: The system (200) is initialized. The system (200) is configured to create a list having details of files that are required to be sent to the primary server or the secondary server. In an example, the file is the XDR file referring to any of CDR (Call data record), MDR (message data record), UDR (user data record, and SDR (session data record). For example, when any error / exception occurs, various XDR records (formatted files) are created in an application, which can be sent to a troubleshooting system. In an example, the XDR file is the CDR file containing information about telephone calls, including details such as the caller's and callee's phone numbers, call duration, time and date of the call, and possibly additional information such as call type (e.g., voice call, video call), call location, and call quality metrics. In another example, the XDR file is the MDR file containing information about messages sent or received through communication channels such as SMS (Short Message Service), MMS (Multimedia Messaging Service), or instant messaging platforms. They typically include details such as sender's and recipient's information, message content, timestamp, and message status (e.g., delivered, read). In an example, the XDR file is the UDR file containing various user-related data collected by telecommunications networks. This may include information about user subscriptions, service usage patterns, billing details, and other relevant data related to user accounts and interactions with network services. In another example, the XDR file is an SDR (session Data Record) file containing information about communication sessions between network elements or devices. These sessions could include various types of network sessions, such as VoIP (Voice over Internet Protocol) calls, data sessions (e.g., internet browsing sessions), or multimedia streaming sessions. SDRs typically contain details such as session start and end times, session duration, involved parties, data volume transferred, and session-related attributes.

[0092] At step 404: The system (200) determines whether a flag is enabled. In an operative aspect, the system (200) may be configured to determine whether a flag is enabled or not. The flag refers to a variable or a value that serves as a signal or indicator of a certain condition or state within the system. For example, if the flag is enabled, then a connection may be established between the network function (204) and the FTP server (including the primary server and the secondary server) for exchanging the files. If the flag is disabled, then no connection can be established.

[0093] At step 406: Based on a positive determination (indicating the flag is enabled) from step 404, the system (200) starts a scheduler (FTP scheduler) with a configurable time. Then, the NF creates a connection with both the FTP servers. The configurable time enables the users to adjust and set various time-related parameters based on specific requirements or operational conditions. This functionality allows for flexibility and customization in managing time-sensitive processes, events, or operations within the system. In an example, the configurable time is a time up to which the scheduler will try to connect with the primary server or the secondary server.

[0094] At step 408: The FTP scheduler starts transferring the formatted files such as to the primary FTP server. The FTP scheduler establishes the first connection with the primary FTP server to transfer the formatted files. The scheduler may be configured to send a request to connect to the primary FTP server to establish the first connection with the primary server. The primary FTP server may acknowledge the first connection or provide an error if the first connection cannot be established.

[0095] At step 410: The system (200) determines if the primary FTP server is connected with the FTP scheduler or not. To determine that the primary FTP server is connected, the FTP scheduler (210) is configured to monitor the state of the first established connection. To monitor the state of the first established connection, the scheduler (210) may be configured to opt for the heartbeatmechanism, in which the scheduler (210) periodically sends heartbeat signals or ping requests to the primary server to verify that the connection is still active. In another example, the scheduler (210) may listen for updates or notifications from the primary server to maintain the relevance of the connection.

[0096] At step 412: If the primary FTP server is connected with the FTP scheduler, the system (200) dumps the XDR files into the primary FTP server. The scheduler (210) is configured to transfer the formatted files to the primary server if the monitored state of the first established connection is the active state.

[0097] At step 414: The system (200) determines a change with the connection with the primary FTP server. If the connection with the primary FTP server is terminated, then the system (200) collects information about the failed XDR files eligible to be dumped to a secondary FTP server. For example, the failed XDR files may be the files for which the system may not receive the acknowledgment from the primary FTP server or maybe the files that are still awaiting transmission. Accordingly, the failed files are sent to the secondary FTP server.

[0098] At step 416: If the primary FTP server is not connected, the system (200) determines whether the secondary FTP server is connected with the FTP scheduler. The network function is further configured to establish the second connection with the secondary FTP server and transfer the formatted files to the secondary FTP server if the monitored state of the first established connection is a down state. To determine that the secondary FTP server is connected, the FTP scheduler (210) is configured to monitor the state of the second established connection. To monitor the state of the first established connection, the scheduler (210) may be configured to opt for the heartbeat mechanism, in which the scheduler (210) periodically sends heartbeat signals or ping requests to the secondary FTP server to verify that the connection is still active. In another example, the scheduler (210) may listen for updates or notifications from the secondary FTP to maintain the relevance of the connection.

[0099] At step 418: Based on a negative determination (indicating the flag is disabled) from step 416, the system (200) is configured to set the flag to false.

[0100] At step 420: Based on a positive determination (indicating the secondary FTP server is connected) from step 418, the system (200) sends the failed files to the secondary FTP server.

[0104] In an embodiment, the bus (520) may communicatively couple the processor(s) (570) with the other memory, storage, and communication blocks. The bus (520) is, e.g., a Peripheral Component Interconnect (PCI) / PCI Extended (PCI- X) bus, Small Computer System Interface (SCSI), Universal Serial Bus (USB), or the like, for connecting expansion cards, drives, and other subsystems as well as other buses, such a front side bus (FSB), which connects the processor (570) to the computer system (500).

[0105] In another embodiment, operator, and administrative interfaces, e.g., a display, keyboard, and cursor control device may also be coupled to the bus (520) to support direct operator interaction with the computer system (500). Other operator and administrative interfaces can be provided through network connections connected through the communication port(s) (560). Components described above are meant only to exemplify various possibilities. In no way should the aforementioned exemplary computer system (500) limit the scope of the present disclosure.

[0106] FIG. 6 illustrates an exemplary flowchart illustrating a method (600) of transferring the plurality of files to the one or more remotely placed servers, in accordance with an embodiment of the present disclosure.

[0107] At step (602), the system, via the network function, receives the plurality of files from a plurality of user equipments. In an aspect, the system receives the plurality of files via at least one P-gateway (202). In an aspect, the plurality of files includes a data file, a video file, and an audio file. In an example, the file is the XDR file referring to any of CDR (Call data record), MDR (message data record), UDR (user data record, and SDR (session data record).

[0108] At step (604), the network function, via the file manager, formats each of the plurality of received files to generate a plurality of formatted files. In anaspect, to format each of the received files, the file manager (206) may be configured to employ a set of formatting steps on each received file according to a specified format or structure to produce the formatted steps. In an aspect, the set of formatting steps may include converting the received files from one file format to another, extracting specific data fields from the received files by employing parsing, and normalizing data within the formatted files to generate a consistent format. To begin the conversion of the received files from one file format to another format, the file manager (206) ascertains a specific file format for each file (For example, PDF, DOCX, JPG, MP4, etc.). Then, the file manager (206) considers and selects a desired format to which conversion of these files is required. This chosen format could be a widely used standard or one that is tailored to meet the unique and specific needs of a network operator. Further, the file manager (206) may be configured to validate the content and structure of the formatted files to ensure they meet a predefined criterion. The predefined criterion may include a size of the file, a compression ratio, and a type of the formatted file (editable or non-editable). In an embodiment, the plurality of formatted files is an XDR file or an abstract syntax notation (ASN) file.

[0109] At step (606), the network function is configured to store the formatted files on a local server.

In an aspect, the scheduler (210) may be configured to send a query to the local server. In an example, the query may include a number of details to be asked the local server. In an example, the query may be an update signal regarding “a current storage of the local server”. Upon receiving the query, the local server processes itand prepares a response. Based on the received query, the local server may be able to provide the response having the current storage of the local server.

[0111] At step (610), the network function establishes a first connection with a primary server based on the determined parameters. To establish the first connection with the primary server, the scheduler may be configured to send a request to connect to the primary server. If authentication credentials are required, the scheduler may include them in the connection request. The primary server may acknowledge the first connection or provide an error if the first connection cannot be established.

[0112] At step (612), the network function monitors a state of the first established connection. To monitor the state of the first established connection, the network function may be configured to opt for the heartbeat mechanism, in which the scheduler periodically sends heartbeat signals or ping requests to the primary server to verify that the connection is still active. In another example, the network function may listen for updates or notifications from the primary server to maintain the relevance of the connection.

[0113] At step (614), the network function transfers the formatted files to the primary server if the monitored state of the first established connection is the active state. The network function is further configured to establish a second connection with a secondary server and transfer the formatted files to the secondary server if the monitored state of the first established connection is a down state.

[0114] In an aspect, the number of parameters includes the current storage of the local server, the maximum storage of the local server, and a time period up to which the files need to be stored.

[0115] In an aspect, the method includes a step of transferring, by the network function, the stored files from the local server to at least one of the primary server and the secondary server after a predefined time. In an example, the predefined time refers to a specific time that is established or set in advance basedon predefined criteria or requirements. For example, the predefined time lies between 15 minutes and 15 days. For example, the system (200) is configured to transfer the stored file from the local server to at least one of the primary server and the secondary server after 1 hour.

[0116] In an aspect, the present disclosure discloses a user equipment communicatively coupled with a system. The coupling comprises steps of receiving a connection request from the system, sending an acknowledgment of the connection request to the system, and transmitting a plurality of signals in response to the connection request.
